Table 1 gives the allowable adjustment range for each model in the series as Va (min) and Va (max). Figure 1 22 Vo(sense) Refer to Figure 1 and Table 2 for both the placement and value of the required resistor, either (R1) or R2 as appropriate. Notes: 1. Only a single 1% resistor is required in either the (R1) or R2 location. Do not use (R1) and R2 simultaneously. Place the resistor as close to the ISR as possible. 2. Never connect capacitors from Vo adjust to either GND, Vout, or the Sense pins. Any capacitance added to the Vo adjust pin will affect the stability of the ISR. 3. If the sense pins are not being used, the resistors (R1) and R2 can be connected to Vout and GND respectively. 4. An increase in the output voltage must be accompanied by a corresponding reduction in the maximum output current. The revised maximum output current must be reduced to the equivalent of 12Watts. i.e. Iout (max) = 12 Va PT6900 +Vin GND Vo(adj) 9 - 15 2 -Vo 16 - 21 Vout(-) GND(sense) 8 (R1) (Down) + Adjust Up: An increase in the output voltage is obtained by adding a resistor R2, between pin 2 (Vo adjust) and pin 8 (Remote Sense GND). Adjust Down: Add a resistor (R1), between pin 2 (Vo adjust) and pin 22 (Remote Sense Vo). 3-7 +Vin C in R2 (Up) + Adjusting the Output Voltage of the PT6900/PT6910 Positive to Negative Converter Series C out L O A D COM COM The respective values of (R1) [adjust down], and R2 [adjust up], can also be calculated using the following formulas.

TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device.
